Utilize unused keys

[pit-ray]

This technique is also used in AHK. You can create your own keys by mapping unused keys into <F*> key which is not on the keyboard.

imap <app> <f13>
inoremap <f13> window_resizer

imap <ralt> <f14>
inoremap <f14> easy_click_left

imap <capslock> <f15>
inoremap <f15> to_edi_normal
